Question 585164: For a standard-position angle determined by the point (x, y), what are the values of the trigonometric functions?
1)....For the point (3, 4), find sin and cos.
2)....For the point (4, 3), find tan and cot.
3)....For the point (3, 4), find csc and sec.

You can put this solution on YOUR website! For a standard-position angle determined by the point (x, y), what are the values of the trigonometric functions?
1)....For the point (3, 4), find sin and cos.
2)....For the point (4, 3), find tan and cot.
3)....For the point (3, 4), find csc and sec.

For all three problems above, the x and y coordinates represents respectively the adjacent and opposite sides of a right triangle with hypotenuse=5, in quadrant I where all the given trig functions>0. You should recognize you are working with a 3-4-5 right triangle.
..
1) sin=4/5, cos=3/5
2) tan=3/4, cot=4/3
3) csc=5/4, sec=5/3
